ADE Advanced Optics Crusader RD3-009 Red Dot Reflex Sight – with Mouting Plate for 1911 with Colt G.I Standard Rear Sight and Picatinny Rail – 5 MOA Reflex – Waterproof, Shockproof & Fog Resistant

Will recomend this to others. Excellent quality.

Worked great until it didn't. Pros: Perfect mount for my Springfield 1911 Milspec, looks like it is a stock part of the weapon. Clean, crisp red dot. Held zero well Docter lug set up Single button for simple operation. Glass optic and metal body. Cons: Sight needs to be removed from the weapon to change battery. Mounting screws are soft and heads stripped out after changing the battery twice. Single button constantly changes brightness setting when powering on or off. Stopped functioning after 500 rounds. Not a bad red dot. Unfortunately it quit working. Ade Optics carries a 1 year warranty, but paying shipping both directions for repair/replacement is hardly worth it. The fact that it stood up to even 1 round on top of a 45 slide impressed me.

Was a little tight going on my Tisas 1911 but shaved a hair off and works great and looks great!

Took a lot of filing to get the base to fit in the rear sight, put 40 rounds through and it flew off and hit me square in the nose, When it worked it works good for the price, need to make some modifications, longer screws and lock tight , then give it another try.

Very good quality. Packaged well. Delivered quickly. Unfortunately would not work on my Kimber. Ordered the ADE base for a different dovetail but still wouldn’t work on the Kimber. Very sad about that! Not the product’s fault!!! Added this set up to my Dad’s Sig Sauer instead and it works awesome!! Highly recommend this sight for a high quality budget red dot!!!

Incredible quality for such a low price, base took a little bit of fitting to my colt commander, but attaches firmly.

Nice unit just impossible to sight in

Worked great, held zero like a champ.
